A .25 g chunk of sodium metal is cautiously dropped into a mixture of 50g of water and 50 g of ice both at 0 C 2Na(s) + 2h2o(l) -> 2naoh(aq) + H2 Delta H = -368 kj Will the ice melt ..
This may not be the answer you are looking for but if the water is at zero and the ice is at zero and you are adding heat you know that SOME of the ice will melt. You don't know if all of it will melt until you calculate it but the problem doesn't ask for that. Nor does it ask for the final temperature.
